Over time, the internal epoxy potting breaks down, leading to voltage leaks and increased secondary resistance. This manifests as high-RPM misfires, sluggish throttle response, and a reduction in towing efficiency. Furthermore, the OEM windings struggle to maintain optimal dwell times under sustained heavy loads, resulting in weak spark propagation and incomplete combustion during off-road or high-stress applications.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis set of 8 replacement UF414 ignition coils is engineered to exceed OEM specifications, utilizing high-grade copper wire for both primary and secondary windings. This reduces internal resistance and allows for faster magnetic saturation, delivering a hotter, more consistent spark. The coils feature upgraded silicone boots and high-dielectric epoxy potting to isolate the spark energy, drastically reducing the risk of arc-over and thermal breakdown. By maximizing voltage output to the spark plugs, these coils ensure complete atomized fuel burn, which stabilizes idle, restores lost low-end torque, and ensures reliable ignition timing under the high-stress conditions typical of a heavy 4x4 platform.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2008-2009 Hummer H2\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e6.2L L92 V8 \/ GMT820\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e393 hp \/ 415 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF414\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2008 Hummer H2 (6.2L V8)\u003c\/li\u003e\n  \u003cli\u003e2009 Hummer H2 (6.2L V8)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Hummer Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for a platform designed to conquer rugged terrain and manage heavy towing demands, these upgraded ignition components ensure your heavy-duty powertrain delivers uninterrupted torque and reliable performance, whether crawling trails or hauling payloads on the highway.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48234178642168,"sku":"DS-EOYIMDZFL","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-performance-ignition-coil-for-hummer-h2-2008-2009-6-2l-1.jpg?v=1776099305","url":"https:\/\/performancechiptuning.com\/products\/high-performance-ignition-coil-for-hummer-h2-2008-2009-6-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
